Synthesis and Crystal Structure of 6-Bromo-2-(furan-2-yl)-3-(prop-2-ynyl)-3H-imidazo[4,5-b]pyridine

Abstract

The crystal and molecular structure of 6-bromo-2-(furan-2-yl)-3-(prop-2-ynyl)-3H-imidazo[4,5-b]pyridine (C13H8BrN3O) has been investigated from single crystal X-ray diffraction data. The primary focus is to investigate the molecular geometry of this compound in the solid state along with the associated intermolecular hydrogen bonding and related π-π interactions present in the crystal packing. This compound crystallizes in the monoclinic space group with cell parameters: a = 4.39655(19) Å, b = 13.5720(5) Å, c = 20.0471(5) Å, β = 94.753(3), V = 1192.10(7) Å3, D = 1.683 g·cm−3, and Z = 4. The crystal structure is stabilized by π-π interactions and intermolecular C–H⋯N and C–H⋯O interactions.
